OBP alloy base mounted round 1 litre capacity fuel swirl pot, with push-on inlets and outlets. It is essential to ensure you keep your motorsport fuel pumps supplied with an adequate amount of fuel in all conditions, braking accelerating, cornering and in bumpy conditions. Swirl pots are used to create a head of fuel for the main pump or pumps to draw from and the swirl pot is usually kept full by one or two high capacity pumps. The fuel is taken from the base of the swirl pot and irrespective of the conditions a head of fuel will remain available to the injection pump(s). There's also a return inlet from the fuel rail for surplus fuel to recirculate from the engine bay, back to the swirl pot. This recirculating of the fuel has the added advantage of cooling the fuel, helping it remain more dense for optimum performance. Features 2 x 10mm inlet pipes, 1 x 10mm top outlet pipe (breather), 1 x 1/2" bottom outlet pipe at the base to supply the injection pump.
